angle by a drop of water falling from the dropping device 7 (the dropsif preferred being projected with some force) which is placed above theslanting portion of an endless wire cloth passing over fourquadrangularly-arranged rollers 3, '-ll, 5, 6, the drops striking thepaper-web between rolls -l and 5. Thereby oval groups of fibers areproduced, with dmvnwardlythickened edges. If the water-drops are causedto fall, however, from a dropping device T located between the rolls 3and r, onto the upper, horizontal part of the wire-cloth and upon a verythin layer of fibers, the patterns produced by these drops show, aftercoaching, a circle inclosing a point which becomes thicker toward thecenter.

If the water-drops are allowed to fall on the lower horizontal part ofthe wire-cloth, between the rolls 5 and t3 and through the "wire, forinstance from a dropping device 7, the drops detach and carryfiber-romplexes down with them, whereupon the fibers still adhering tothe wire-cloth and passing between the rolls (3 and 11 may either becouched upon the specially-preparedv continuous paper-web on the endlesswire 8, and the-drops loaded with the detached fibers collected andremoved, or the drops loaded with paper-fibers may be allowed to fallupon the paper-web on the endless wire 8, as indicated at 8.Furthei-more, the paper-fibers or fiber-complexes carried along with thedrops, as well as the fibengroups still adhering to the wire 2. 1'nay beput on the continuous papei wcb. The attachment of the fiber-complexescarried along with the drops to the paper-web can be etl'ected either byallowing the drops to fall directly upon the paper-web, as by T, 7, orby "Howing them to first fall upon wire-cloth and then couching upon thepapenweb the groups of fibers thus formed; or by depositing groups offibers upon a supplementary distributor, such as a wire-cloth cylinder2t), as shownin Fig. 2, and then causing the paper-web 21 to run uponthe groups of fibers formed upon this intermediate wire cloth.

In order to etl'ect the desired breaking up of the layer of fibers, orthe throwing oil of fiber particles, there may be employed, instead ofwater-drops, water sprayed under high pressure, or compressed air.delivered for instance by jet-pipes 1:2 and 1 The action of thejet-pipes may be periodical, and they may moreover be arranged so as tomove laterally, as shown in Fig. 5 When. employing water, which drainsthrough the layer of fibers to be broken up, or which drops through it,for instance from the de vice 7, Fig. 1, there may be provided a reboundpiece'il, on that side oi the wire-cloth which is free from papermlp.10, 10 indicated at certain points in Figs.

The gutters layer of fibers to be broken up. Water or very thinpapenpulp of a. different color may also be thrown against the layer offibers on the oblique part of the wire-cloth 23', as in.- Fig. 3. bymeans of some system of ladies 24, whereby peculiarly displaced patternsare obtained.

if water is thrown from the back of the wire-cloth 25 aggjainstv thelayer of fibers to be broken 1),415 by a jet 26, Fig. 4, and the wateris drawn away by a. suction apparatus or gutter 27, the breaks inthepaperweb have an indented edge. It colors are sprayed at an acuteangle, for instance by means of spraying nozzles 14, Fig. 1, onto thefibers or groups of fibers which have been partly displaced from thesurface of the wire-cloth, or lifted up in consequence of the breaking,up of the layer of fibers by pressure applied from the lower or inferiorpart of the wire, for instance bymeans of air or a liquid pressed fromjet-pipes 13, then the groups of fibers are colored on one side. Thegroups of fibers thus treated have, after being couched upon the otherpaperweb, a reliefdike appearance on the paper.

The water which has penetrated from the back. as from 28, Fig. 5, andthe fibers carried along with it, can be collected or thrown back on thewire-cloth by means of co1npressed 'air as from the jet 2.). In thelatter case a more blurred pattern is obtained. If

two such'layers of fibers of (.lir'l'erent colorare couched upon thepaper-web. one over the other, the marbling becomes tricolored.

By periodically spraying on. the paperweb diluted paper-pulp ofdifi'erent color. as by means of high pressurewater-pipesi 30. 31, Fig.(3. at difierent angles and from different sides, from. nozzles whichmay be movable, for example as shown in Fig. 8. if preferred'nsingrebound plate S1 close behind the Wire, as shown in Fig. 6, peculiarcloudy pictures are obtained. Pcculiar breakings of the layer of fibersmay also be obtained as .in Fig. 7, by means of differently arranged anddifferently moving 'et-pipes 32, 33 f-r orn which air or Waterispressed-i JVhen water is pressed from jet-pipes 34:,

Fig. 8,v which, while oscillating like a pendulum over the slanting partof the viiire, periodically act upon the layer of fibers at anacute-angle, the so-called tiger-spotted pattern is obtained. A rotatingroller providedalong its length witlistrips of felt, 36, Fig. 9, andacting upon the layer of fibers produces the same ell'evt.

Other means for breaking up and displacing the layer of fibers are, asshown in Fig. 10, stifi' tissues, cloths, or ropes 37,'and rollerscoated. with felt 38, whalebone reeds arranged in the form ot'rrollersor rods, or similar devices with a rotary or sliding action, such asdescribed in U. S. Patent from a jet-pipe l8 placed at the lower sideClearly-defined patterns can be obtained by means of a stencil 39 madefor instance ol india-rubber cloth, Fig. 11, running along with theWire-cloth and lying close to'it. The pressure device ll), Fig.1 or 43of Fig. :12, is caused to act through this stencil upon the layer offibers to be broken.

up. This stencil may also be arranged so as to run more quickly or moreslowly than the wire-cloth, or to more laterally thereto. l'Vhen using astencil 41, a suction-roller 42 may be employed as shown. in Fig. 12,its stead of the pressure-device of Fig. 11,

for breaking up the layer of fibers in a de tel-mined pattern. In. usinga press-roller, this roller may replace one of the guiderollers lor 5,of Fig. 1.

A layer of fibers couched from the Wirecloth lel, upon a felt 45, as inFig. 13, may be treated insuch a manner that the felt 45 with the layerof fibers runs over a suction roller 46 provided with slits, which sucksup the fibers in strips, through the felt. If a spray of water driven byhigh pressure from jet 4'!" is now caused to act at an acute angle uponthe layer of fibers, the fibers which have not been sucked up are massedtogether. The pattern thus obtained shows, after being couched upon thepaper-Web,

edges thickened on one side.

Some working methods may also be carried out upon. an entirelyimpermeable substratum as in Fig. M. For instance a layer of fibersrunning on canvas 4&8 can' be treated with the aforementioned stencil a9and a water-spray o0. The fiber is thereby partially floated, and mustfirst be taken up by a felt 51 running through a press and thentransferred onto the paper-Web 52.

Multicolored 'marblings may, as shown in Fig. 15, he produced bycouching one over the other several difierent layers of'fiberspreviously treated upon a number of wirecloths 53, 54, The thus-preparedmuch broken-up layer of fibers is then transferred to-the base paper-web56, For this method, cylindrical wire-cloths are also suitable, and itis not necessary that the wire-cloths be deeply covered.

The drawing in Fig. 1 also illustrates means for practising the newprocess when using endless wire-cloths,or when it is 111- tended to makepapers with patterns on both sides, this case the papenpulp for thelayer of' fibers to be broken up runs from a supply pipe 15 onto theendless wire-l,

of the wire and penetrating through the wire. Upon the layer of fibersbroken up as above-mentioned or by any other means,

if preferred by simultaneously using stencils'or suctionorpressure-rollers, the paper-pulp for the real paper-web is run. Inorderto obtain papers colored on both sides, a. second broken-up layer offibers, produced for instance by the frame-Wire arrangement, can beapplied to the upper side of the paper-web in the above-describedmanner, by couching or throwingit on the latter.
